Abstract

The invention discloses a 1394 data collection module, comprising a power PC main processor and a plurality of 1394 links. The power PC main processor is connected with the plurality of 1394 links. Each 1394 link comprises a 1394 link layer chip, a 1394 physical layer chip and a plurality of ports. A power PC is connected with the 1394 link layer chip. The 1394 link layer chip is connected with the 1394 physical layer chip. The 1394 physical layer chip is connected with the plurality of ports. Each port realizes one bus. Data output by a plurality of buses realized by each 1394 link is the same. Through application of the scheme of the embodiment of the invention, the number of connections among modules and the number of data transmission channels are increased, and the accuracy and reliability in the data transmission process are improved.

Description

technical field [0001] The invention relates to data acquisition technology, in particular to a 1394 data acquisition module. Background technique [0002] With the rapid development of the IEEE Std 1394-1995 technology of the Institute of Electrical and Electronics Engineers, IEEE 1394 has become the basic external interface of many electronic devices. The most commonly used 1394 data acquisition card in consumer electronics is a DV acquisition card, one side is a PCIe metal finger structure, and the other side is a video interface, used to transmit image data; in industrial applications, the most commonly used is an interface adapter card, generally There is no processor on the connection card, it only provides interface conversion function, and supports a link with up to 3 ports. The 3 ports include: 2 9pin 1394 ports and 1 6pin 1394 port, which are used to transmit large data. Because this structure contains only one link, the scalability of the current 1394 data acquis...
